ASRock Rack X570D4U micro-ATX server motherboard AM4 4×288 DDR4 3200 12 SATA 2×1GbE

Server motherboard AM4 micro-ATX

The ASRock Rack X570D4U is a micro-ATX server motherboard built around the AMD X570 chipset and Socket AM4 PGA 1331. It accepts AMD Ryzen 5000, 4000 and 3000 series desktop and PRO processors, including G-Series models with Radeon graphics. The board targets compact 1U or 2U chassis that need integrated IPMI and dense storage connectivity.

Builders needing ECC DDR4 and 12 SATA ports

This board suits builders who want ECC UDIMM support across four 288-pin slots running at DDR4 3200 and up to twelve SATA 6.0Gb/s ports with RAID 0, 1, 10. Dual Intel I210 1GbE ports plus a dedicated IPMI LAN give basic remote management. It is not for systems requiring 10GbE onboard, more than three PCIe slots, or a second M.2 slot wired from the CPU.

PCIe 4.0 x16 slot from the CPU

The single specification that decides fitment is the CPU-attached PCIe 4.0 x16 slot (SLOT6), which drops to x8 when the open-end PCIe 4.0 x8 slot (SLOT4) is populated. With a second-generation Ryzen processor this slot runs at PCIe 3.0 x8, so the chosen CPU generation directly determines the available expansion bandwidth.
